Benefits of technology

The system effectively cuts hard materials with reduced pressure requirements, minimizing thermal damage and allowing for precise cutting patterns, while maintaining nozzle performance and biocompatibility.

Problems solved by technology

One drawback associated with current fluid pressure-based surgical systems which are used to cut bone and the like is that they typically require ultra-high operating pressures, and the delivery of such hydraulic pressure using a conservatively sized operating room pump and surgical instruments delicate enough to meet the surgeon's demands can often be problematic.

Abstract

A high pressure fluid jet system is provided, which is useful for cutting hard material during a surgical procedure. The cutting of hard material is more efficient as the system delivers abrasive solid particles with the high pressure fluid. A method of effecting cutting during a surgical procedure is also provided. In an exemplary embodiment, a surgical tool that is effective to deliver a pressurized stream of fluid through a nozzle is provided, and the pressurized stream of fluid is delivered through the surgical tool and out of the nozzle to hard material within a patient to effect cutting of the hard material within the patient in a desired pattern. The fluid that cuts the hard material can include a delivery liquid having a plurality of abrasive solid particles that are formed from an organic material. The abrasive solid particles can be entrained in the pressurized fluid stream or the pressurized fluid stream can erode a solid or suspension form of the abrasive particles.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. Patent Application Publication No. 2006 / 0142773 filed on Dec. 29, 2004, entitled “Abrasive Cutting System and Method,” and now abandoned, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to high pressure fluid jet surgical tools, and in particular to a high pressure fluid jet tool for cutting hard material during a surgical procedure.BACKGROUND OF THE INVENTION[0003]Fluid pressure-based surgical tools for cutting bone and the like can offer some advantages over traditional surgical cutting devices and methodologies. In particular, high pressure fluid jets tend to emulsify the target material, thus avoiding thermal damage which can arise from using laser cutters and electrosurgical cutters. The emulsified material can also be easily transported away from the surgical site by aspiration. Indeed, the fact that many high pressure fluid ...
